No log for error?

Over looked it plenty of times and can't figure out anything wrong with this code. I try to look in the log section but it just glitches a little with a white screen then goes blank. Any ideas?

struct.swift 
struct Expense {
    var description: String
    var amount: Double = 0.0
    var item : String

    init (description: String, item: String) {
        self.description = description
        self.item = item
        amount = 100
    }

    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double
    func calculateTaxes(percentage: Double) -> Double {
        return (self.amount * (percentage/100))
    }
}

I Don't know whats happening with the log but I do know what you did wrong. what you did is you created the variable item inside the struct instead of the global scope you also defined item as a String which you didn't have to do you had to create an instance by typing

var item = Expense(description: "Something")

here is all the code for the part your on

struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String) {
        self.description = description
    }

   func calculateTaxes(percentage: Double) -> Double {
   return self.amount * (percentage/100)
   }
    // it should accept only one parameter named 'percentage' of type Double

}

var item = Expense(description: "Something")
item.amount = 100

and here is all the code for tasks 1 through 4

struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String) {
        self.description = description
    }

   func calculateTaxes(percentage: Double) -> Double {
   return self.amount * (percentage/100)
   }
    // it should accept only one parameter named 'percentage' of type Double

}

var item = Expense(description: "Something")
item.amount = 100
var taxes = item.calculateTaxes(7.5)
